At the World Economic Forum in Davos, Switzerland, recently, Minister of Petroleum and Natural Gas said that India will emerge as the leader of green hydrogen by taking advantage of the current energy crisis across the globe.

About

Green hydrogen:

  • Green Hydrogen is colourless, odourless, tasteless, non-toxic and highly combustible gaseous
  • Hydrogen is the lightest, simplest and most abundant member of the family of chemical elements in the universe.
  • Green hydrogen is produced through electrolysis using renewable sources of energy such as solar, wind or hydel power.

  • Grey hydrogen is generated through fossil fuels such as coal and gas and currently accounts for 95% of the total production in South Asia.
  • Blue hydrogen is produced using electricity generated by burning fossil fuels but with technologies to prevent the carbon released in the process from entering the atmosphere.

Green hydrogen is India:

  • Under the Paris Agreement (a legally binding international treaty on climate change with the goal of limiting global warming to below 2°C compared to pre-industrial levels) of 2015, India is committed to reducing its greenhouse gas emissions by 33-35% from the 2005 levels.
  • At the 2021 Conference of Parties in Glasgow, India reiterated its commitment to move from a fossil and import-dependent economy to a net-zero economy by 2070
  • In order to become energy independent by 2047, the government stressed the need to introduce green hydrogen as an alternative fuel that can make India the global hub and a major exporter of hydrogen.
  • India has just begun to generate green hydrogen with the objective of raising non-fossil energy capacity to 500 gigawatts by 2030.
  • In April 2022, the public sector OIL, which is headquartered in eastern Assam’s Duliajan, set up India’s first 99.99% pure green hydrogen pilot plant in keeping with the goal of “making the country ready for the pilot-scale production of hydrogen and its use in various applications”.
  • The plant was set up at the petroleum exploration major’s Jorhat pump station, also in eastern Assam.
  • Powered by a 500 KW solar plant, the green hydrogen unit has an installed capacity to produce 10 kg of hydrogen per day and scale it up to 30 kg per day.
